我国社会保障财政支出效率区域差异研究

Study on Regional Differences in the Efficiency of Social Security Fiscal Expenditure in China

如何提高社会保障财政支出效率是新时代亟待解决的问题。利用2008-2017年的省级面板数据,采用DEA-Tobit模型,测算我国社会保障财政支出效率以及影响各区域效率的因素。先用DEA模型从静态的角度测算2017年我国各省份社会保障财政支出效率水平,再采用Malmquist指数法从动态的角度对我国2008-2017年社会保障财政支出效率的变化进行深度剖析,并通过聚类分析对2017年社会保障财政支出的DEA效率值进行分析,可以将各省份分为四类,最后采用Tobit回归模型探讨影响各类省份社会保障财政支出效率的因素。研究发现,我国社会保障财政支出效率以及影响因素均存在明显的区域差异,应采取政策分类指导的方式提高社会保障财政支出效率,完善社会保障体系。

How to improve the efficiency of social security expenditure is an urgent problem to be solved in the new era. Using the provincial panel data from 2008 to 2017, the DEA-Tobit model is adopted to calculate the efficiency of China’s social security fiscal expenditure and the factors affecting the efficiency. DEA model first estimates 2017 provinces in China from the perspective of the static efficiency of social security expenditure level, and then using the Malmquist index method from the Angle of dynamic in 2008-2017 in our country social security expenditure efficiency changes in-depth analysis, and through cluster analysis, provinces of social security expenditure efficiency can be divided into four categories, then with Tobit regression model, we are to investigate the factors that influence efficiency of social security expenditure various provinces. It is found that there are obvious regional differences in the efficiency of social security fiscal expenditure and the influencing factors in our country.
